Modern sensors, like digital and video cameras, measure huge amounts of data day-by-day. Pattern Recognition and Image Processing aims at the extraction of information from such data.

Usually, the information to be extracted is related to pieces of data from the same environment that gives them meaning. Typical applications are tasks like autonomous navigation, the detection of anomalies in medical images or the prediction of an eruption of a volcano.

Simple tasks like the detection of human faces are already solved and solutions are commercially available in digital cameras. However, there is still a large number of complex tasks that require the system to incorporate knowledge to be efficiently used to enhance the recognition results and to give semantically appropriate interpretations. Such knowledge could be about the characteristics of the camera system, the composition and structure of the environment or the available processing strategies.

The large amount of data to be processed requires sophisticated representations that are both efficient and robust with respect to noise and distortions in the measurements.

Some problems may seem hopeless to solve at a first glance, but there are wonderful "natural" systems solving extremely hard tasks nearly effortlessly. We can learn by better understanding the human/biological perception mechanisms.

Development of a pose-independent representation of 2D horse shapes
Master's thesis/Practicum/Bachelor thesis

The Spanish Riding School with its Lipizzan horses is one of the most famous tourist attractions in Vienna. In breeding, it is desirable to objectively evaluate the traits of a Lipizzan horse based on quantitative measurements. Unfortunately, traditional approaches of measurement lead to a low repeatability rate due to pose changes of the horse and/or differences between the measurement techniques of different people.

The aim of this thesis is to develop a representation of a 2D horse shape, which is independent of pose OR to develop an approach which is able to “normalize” the current pose of a horse to a standard-pose.

Ermittlung der Klebstoffverteilung in Spanplattenquerschnitten
Diplomarbeit/Praktikum/Bachelorarbeit aus Visual Computing

Die Forscher am Kompetenzzentrum für Holzverbundwerkstoffe und Holzchemie arbeiten daran, die Menge und Verteilung des Klebstoffes in Spanplatten zu optimieren. Ihr Ziel ist es, die Menge an verwendetem Klebstoff möglichst weit zu reduzieren/optimieren ohne die Stabilität des Plattenwerkstoffs zu beeinflussen. Durch ihre Forschung sollen Ressourcen und Kosten eingespart werden.

Momentan werden die Mikroskopaufnahmen in einem aufwendigen Prozess manuell analysiert. Ziel dieser Diplomarbeit ist es diese Analyse weitgehend zu automatisieren.

2D tracking of Platynereis dumerilii worms during spawning
Master's thesis/Practicum/Bachelor thesis

The marine annelid Platynereis dumerilii reproduces by external fertilisation and is semelparous, meaning that it spawns only once in its lifecycle. To maximise reproductive success these worms synchronise their spawning events with the lunar cycle and spawn primarily during new moon (Zantke et al., Cell Reports, 2013). In addition, P. dumerilii exhibit particular swimming behaviours during spawning, which are collectively described as a ‘nuptial dance’. The nuptial dance is initiated by excreted pheremones, stimulating male and female worms to swim in circles around one another and finally release sperm and eggs into the water.

The aim of thesis is to develop methods that enable 2D tracking of spawning worms from captured video and extract data to quantify specified behaviours.
